IMPROVEMENT m TnEMANUFAc-TuRE'oF SPIRITS FROM s'rARcH.

The schednle referred to in these Letters Patent and makingpaxt of the same.

To all whom it may concern Be'it known that 51," HERRMANN- Kosnnnn, of the city,'county, and State of New ,York, have invented a new and useful Improvement 'inManufacturing Whisky from Starch and Ido hereby declare the following. to be a fnll, clear, and exact description thereof, which will enable those skilled inthe'art'to make and use the same.

This inrention consists in producing whisky-from starch, by first preparing from the starch a thin mash,

thent'reating this mash with sulphuric acid, so as to produce a sirup of about 15 Baurn', then COHOQH'. trating this ,sirnp, by-tneans of a vacuum pan or other suitable apparatns,to38? Baum,'and finally, allowing it to ferment, and subjecting it to thedistilling op- 1 .eration in any suitable apparatus. i

In carrying outiny invention, I l take starch prepared from corn, or any other material generally used a for this purpose, andfrom thisstarch I prepare athin mash, by mixing it with a suflicient quantity of: water. To this mash I addsulphnric acid, whereby the starch is transformed into glucose, and a .sir up'is obtainedof the density of about 15? Baum. .r

' Ilhis s'irup I snbject't-o ac'oncentrating process, by evaporation in a vacuum pan or other, suitable appay tns, until its density is about 138 Baum. I

The concentrated sirup thus obtained Iallow toferment, and then I subject it to a distilling process in any suitable apparatus.

By these means I am enabled to produce a liquor, which is superior in aroma and in purity to ordinary whisky, and'which can be manufactured at a comparat-ively low I figure.

WhatvI claim as new, and desire to secure by-Let ters Patent, is-- V v 'The within-described processfor manufacturing whisky', consisting of treating a thin mash of starch with an acid, and then evaporating, fermenting, and

distilling the same,substantially as described.

I'Ihis specification signed by me this 29th day of August, 1870.
